Unsuitable Practices for Immunization in Meat Dog Farming

To do a good job in the prevention and treatment of dog diseases, before immunization, meat dogs should undergo a health check and body temperature measurement. Dogs in poor body condition should temporarily not be vaccinated, and immunization can be carried out after recovery from illness or weaning to ensure the immunization effect.

Nursing puppies should not generally be vaccinated. Puppies under 30 days of age may temporarily not be vaccinated. Because if the mother dog has been vaccinated, the puppies can obtain maternal antibodies when they consume colostrum. If puppies are vaccinated within 30 days of age, immune interference will occur, so nursing puppies should not be vaccinated. Clinically, puppies receiving their first vaccination must be over 50 days of age. Pregnant female dogs should not be vaccinated, especially female dogs more than 1 month pregnant and female dogs about to give birth. Because restraint and injection can easily frighten the female dog, which can easily lead to jostling and pressing on the abdomen, causing miscarriage. Female dogs within half a month after giving birth should not be vaccinated, because at this time the female dog is in the peak lactation period. After vaccination, fever and local inflammation with redness, swelling, heat and pain will appear, affecting lactation. Sick dogs should not be vaccinated, because during the period of illness the dog's disease resistance declines, vaccination will aggravate the condition and also affect antibody production. Dogs that have just been castrated or dogs with unhealed trauma should not be vaccinated. In this case, vaccination will aggravate the stress response and is also unfavorable for wound healing. The wound is not easy to heal, which may lead to infection and interfere with the immune response. Antibiotics must not be used during vaccination. Tests have shown that most antibiotics can change the osmotic pressure or pH of the diluent, have varying degrees of inhibitory and killing effects on bacteria or viruses, reduce vaccine activity, and affect the effect of immunization. In particular, antibiotic solutions must not be used to dilute vaccines. It is not advisable to blindly increase the vaccine dose. When vaccinating with most vaccines, under the premise of ensuring correct use, the vaccination dose indicated in the instructions may be used. Increasing the dose without authorization will cause unnecessary waste and may even lead to immune paralysis.
